This one is going to be hard, there are lots of reds that look alike.
Here's a guess. Daylily (Hemerocallis 'Red Volunteer')
Where did you get it?
If you got it from a nursery or a garden center it's probably a popular one which we might be able to ID it.

I know it is a long shot. It was in MN at restaurant.

If the flower was really big, about 7". I would still say it's Red Vounteer.
It's one of the most popular red daylilies.
